Crystal Structure of 1-(3,5-Dichloro-2,4-difluorophenyl)-3-(2,6-difluorobenzoyl)urea, an Inhibitor of Chitin Synthesis

The crystal structure of 1-(3,5-dichloro-2,4-difluorophenyl)-3-(2,6-difluorobenzoyl) urea, an inhibitor of chitin synthesis, has been established; the crystal belongs to the triclinic system but with Z = 6 and there are three molecules of different conformations in each asymmetric unit; the urea linkage was coplanar for the formation of an intramolecular hydrogen bond.
